    • RE: Z Input Shaping

      @dc42 Interesting, I didn't realize it was being applied to the Z axis as well. I will experiment with different shaping parameters and see what happens. Thanks!

    • RE: Z Input Shaping

      @dc42 I have a very large CoreXZ printer with an XY plane that is 45 degrees about the X axis from the XZ plane. The printhead moves in the XZ plane with the nozzle normal to the plane. The bed lies in the XY plane and slides along the Y axis.

      All this to say that input shaping along the Z axis would be very helpful to me as the printhead is routinely moving at high speeds in that direction. Also, I know the duet wiki gives some good reasons why you normally wouldn't want to independently configure input shaping for each axis, but in my case this would be very helpful as well since the frequency response of my machine in the Y direction is very different than the X direction. My machine is admittedly not the norm, but seeing these features would be a big plus to me.

      Also, if anyone has any ideas on workarounds to implement Z axis input shaping with the current firmware, I would love to hear them.

    • RE: SD Card Corruption and Board Reset Issue

      @droftarts thanks so much for your response, sorry I somehow missed it until now. I'll keep a better eye out in the future.

      I am using Clearpath SDSK servo motors that are powered independently of the board, but in my config.g file I have the currents set to 800mA each.

      The board is enclosed but I do have a fan that is cooling the enclosure and the board. When I take the board out of the enclosure into open air I see no change in behavior.

      Since my last SD card switch (May 22) the machine hasn't shut down like before and unfortunately I did not save any of my M122 reports from after a crash. Here is one from today though:

    • SD Card Corruption and Board Reset Issue

      I am in the process of building a large-format 3d printer and I am using a duet 2 ethernet board at the moment.

      A few weeks ago the board would start to shut off and reset itself intermittently, with resets becoming more and more frequent the more the board was being used. The MCU temperature was also rising, and the shut-offs would usually occur between 55 and 70 degrees (before, it never really got above 45 during use). I tried lots of hardware solutions as well as re-uploading the firmware (I was using 3.4.6 when the problem first started and now I am using 3.5.1), but the problem persisted.

      Finally, I tried using a different SD card and it solved the problem, or at least, it fixed the problem temporarily. A week later the same problem popped up again and so I switched to yet another SD card. This worked for about a week again and now the problem is back.

      It seems the board is corrupting the SD cards, but I don't know why and I'm not sure this is the root of the problem. Does anyone have any ideas of what it might be and how I can troubleshoot this? Happy to provide copies of my config.g files and such if necessary but as a new user here it seems I don't have the privilege of uploading files yet
